Preserving Historic Stone Monuments
| The historic monuments at Vicksburg National Military
Park come in all shapes and sizes. From granite to marble, porous to polished, the
stonework varies in density, type and composition. Regardless of the treatment used,
the utmost care must be taken to avoid damaging the delicate surfaces of the commemorative
stone memorials. The physical characteristics of the stone determine which methods are
used. At right, a high pressure water spray is usually the first step in removing
dirt, grime and surface contaminants. The water can be applied hot or cold,
under high or low pressure, but it may require protective clothing and safety
equipment. |

The preservation of stone often requires unique and
specialized methods. Although water has excellent results on most stonework,
sandblasting is a popular alternative on extremely hard surfaces. |
| Unfortunately, monuments are located at points throughout
the 2,000 acre battlefield. Whether its situated on a hilltop or at the bottom of
the ravine, monuments must be easily accessible for preservation treatments to occur.
This requires the use of equipment which is portable, durable and can be
easily moved within close proximity of the structures. |
